Warning!
Unfortunately, regulation and implementation in respect of cannabis seeds often differ from country to country. For this reason we advise you as a matter of urgency to make inquiries about the regulations to which you are subject. Read the complete disclaimer here.

Cannabis seedlings usually emerge from the growing medium 24 to 72 hours after the germinated seeds are planted.

Step 1. The setup – How to germinate cannabis seeds

Seeds should be placed on top of the tissue, allowing each seed as much space as possible.

This article explains how to correctly germinate your cannabis seeds, covering everything from optimum temperatures, to potting your seedlings and transferring them outdoors (or inside under lights).

Check the seeds every day to ensure that the tissue does not dry out. Spray the tissues with water if necessary.

If you look closely at a cannabis seed, you will notice that it has a slightly oval shape, ending in a point at one end and forming a small “crater” at the other end, which is called the crown. When planting your seed (whether it’s a seed that you want to germinate, for example, in a jiffy, or a seed already germinated on kitchen paper that you want to transplant) you must keep in mind that this crown should always be facing upwards.

So, you should plant the seed with the tip down and the crown uppermost and facing you. Once the seed germinates the crown will serve as a hinge, so that the seed will open at the tip and let out the root. In case of placing the seed incorrectly, the tap root will grow upward and the seedling downwards, which should be avoided at all costs because it is likely that the seedling will not be born.

Cannabis seeds germinate correctly with relatively high temperature and humidity values. It will be necessary, especially during some seasons of the year, to use some source of heat to get a temperature of about 26-28ºC. For this purpose there are many options on the market, such as thermal cables or heated greenhouses. The latter are particularly interesting because they also provide the perfect high humidity environment for seed germination.

Temperature and humidity for germination

To obtain much better results, first germinate seeds in kitchen paper, jiffy pellets or peat plugs used for rooting cuttings and then transplant them to the soil or to a pot once the small seedlings have been born. Another benefit of this method is that we can germinate a large number of seeds in a very small space, such as a small greenhouse, which will make it much easier to provide the correct temperature and humidity.

Although it may be tempting, germinating several seeds in the same container is not usually successful. In addition to the difficulty of correctly planting several seeds in the same pot, once they are born they will compete for the little space available for their roots. Having restricted root growth does not suit cannabis plants, which will grow more weakly and with greater internodal distance.

To avoid these problems it is be best to sow the seed at about 2cm depth. In addition, we can cover the lower stem as the seedling grows, so that it gains stability and produces new roots along the length of stem we have buried. In this way we can accelerate the growth of the plants.

This is a common mistake that usually results in non-germination, especially if the substrate hasn’t been previously watered before sowing the seed but is watered afterwards. By planting the seed directly in the substrate, we run the risk of it being buried too deep, made worse when we irrigate the growing medium post-sowing.
